"  The  works  of  God  are  so  worthy  of  their  author,  that  besides  the  impresses  of  his  wisdom  aud 
goodness  that  are  left  as  it  were  upon  their  surfaces,  there  are  a  great  many  more  curious  and 
excellent  tokens  and  effects  of  Divine  artifice  in  the  hidden  and  innermost  recesses  of  them ;  and 
these  are  not  to  be  discovered  by  the  perfunctory  looks  of  oscitant  and  unskilful  beholders ;  but 
require,  as  well  as  deserve,  the  most  attentive  and  prying  inspection  of  inquisitive  and  well- 
instructed  considerers.  And  sometimes  in  one  creature  there  may  be  I  know  not  how  many  ad- 
mirable things,  that  escape  a  vulgar  eye,  and  yet  may  be  clearly  discerned  by  that  of  a  true 
naturalist." — Boi/le.

SPONDYLUS. 


Genus  SPONDYLUS.  Lnni^tus.

qm  valvfl,  valide  intersertis,  ligamenUmi  in  cavHalem 
inter  se  recipleiitibns.     Impressio   muscularis   mbla- 
teralis. 
Shell  attached,  inequivalve,  irregular,  more  or  less  auricu- 
lated,  radiately  striated  and  ridged,  rarely  ribbed,  va- 
riously prickled  and  spined ;  umboes  equal,  peculiarly 
separated  by  a  very  large  flat  hinge  area,  more  and 
more  produced  with  age.     Hinge  with  two  solid  re- 
flected teeth  in  each  valve,  strongly  interlocking,  and 
receiving  the  ligament  between  them.     Muscular  im- 
pression sublatcral. 
The  Spondylus,  or  Thorny  Oyster,  is  one  of  the  earliest 
known  shells.    When  Aristotle  occupied  himself  with  phi- 
losophic interest  in  describing  the  animals  of  the  Mediter- 
ranean, the  -S".  (jftdaropus  lived,  as  now,  in  all  its  royal 
panoply  of  purple  and  white,  and  the  name  adopted  by 
Linnaeus  when  engaged  upon  the  grand  formula  of  nomen- 
clature which  has  become  the  law  of  naturalists,  was  that 
of  the  old  philosopher  of  Greece,  namely,  SiroVSuXos.    The 
species  added  to  this  genus  in  modern  times  are  compa- 
ratively few ;  Lamarck  numbered  twenty-one ;  Sovverby,  in 
liis  recent  monograph  in  '  Thesaurus  Conchyliorum,'  only 
thirty-four,  and  I  have  but  two  or  three  to  add.   The  species 
are  mostly  well  known  to  collectors,  all  having  an  attrac- 
tive interest  from  their  singularity  of  form  and  beauty  of 
colouring.     Their  grow'th  is  peculiar  and  extremely  irre- 
gular, varying  according  to  the  circumstances  of  their  place 
of  attachment ;  it  may  be  remarked,  however,  that  it  is  on 
the  upper  valve  that  the  shell  developes  its  truest  specific 
cliaracter. 

The  Sporiihjll  are  confined  to  no  particular  locality. 
Limited  as  they  are  in  species,  they  are  distributed  very 
generally  over  the  globe  south  of  the  latitude  of  the  Medi- 
terranean.    There  are  no  sjiecies  on  the  coast  of  Britain. 

Species  1.  (Mus.  Cuming.)

The  Pacific  Spondylus.  Shell  obliquely  broadly  tri- 
angularly compressed,  radiately  finely  imbricately  stri- 
ated and  ridged,  ridges  somewhat  twistedly  flexuous. 
very  finely  scaled,  scales  sometimes  almost  obsolete; 
ruddy  or  rose-coloured,  sometimes  whitish,  rayed  with 
vermilion. 
Ilab.  Lord  Hood's  Island,  Pacific  Ocean ;  Cuming. 

This  species  has  been  sometimes  regarded  as  a  variety 
of  S.  ««(/h.s  which  follows,  but  it  is  uniformly  distinguished 
by  a  characteristic  obliquely  triangular  compressed  growth, 
rayed  with  exceedingly  fine  squamate  ridges  and  striae. 
Mr.  Cuming  possesses  it  in  several  varieties.

The  denuded  Spondylus.     Shell  somewhat  elongately 
triangular,  gibbous,  rotundately  swollen  towards  the 
umboes,   radiately  densely    striated   and    sometimes 
ridged,  strife  scarcely  imbricated,  nearly  smooth,  pos- 
terior ridges  sometimes  scaled  towards  the  margin, 
auricles  smooth ;  bright  scariet,  generally  rayed  with 
distant  white  lines.

Hab.  Mauritius  and  Philippine  Islands  ;  Cuming. 

A  richly  painted  vermilion  shell,  mostly  rayed  at  rather 
distant  intervals  with  white  lines.  It  is  at  once  distin- 
guished from  the  preceding  species  by  its  elevated  regular 
gibbous  growth,  and  ab.sence  of  scales,  except  in  advanced 
specimens  at  the  ends  of  the  posterior  ridges.

with  very  irregular  short  squaraate  spines,  upper  valve 
rayed  near  the  umbo  with  three  small  sharp  sealed 
ridges,  lower  valve  generally  much  foUated  and  cham- 
bered ;  white,  stained  around  the  umbo  with  pui-jjle- 
rose  and  orange,  the  three  small  radiating  ridges  be- 
ing darker  in  colour.

This  tine  species  is  distinguished  in  all  its  stages  ol' 
growth  by  three  widely  separated  fine  squamate  ridges 
radiating  from  the  umbo,  of  a  darker  red  tiut  than  the  sur- 
rounding colour  of  the  shell.  It  is  of  very  irregular  growth, 
sometimes  depositing  a  series  of  basal  laminae  in  the  lower 
valve  one  over  the  other,  and  hermetically  closing  water  in 
the  chambers,  in  which  state,  often  of  great  size,  it  is 
known  to  collectors  by  the  name  of  the  Water  Spondylus.

Hal).  Seychelle  Islands. 

This  well-known  species  is  chiefly  distinguished  from  its 
nearest  ally  S.  Butleri,  by  the  sharp  curved  prickly  cha- 
racter and  abimdance  of  the  spines,  and  by  the  absence 
of  marking  in  the  vicinity  of  the  umbo.

scurely spotted  throughout  with  yellow,  clouded  with 
blood-smears,  and  very  prickly  about  the  umbo. 

Hah.  Philippine  Islands ;  Cuming. 

It  is  a  striking  characteristic  of  this  species  to  be  every- 
where crowded  with  small  prickles,  iu  addition  to  the 
prickly  spines.

contrast  of  colouring ;  the  upper  valve  being  of  a  uniform 
rich  purple,  whilst  the  lower  valve  is  white,  partially 
tinged  with  orange.

spines  strong,  rather  erect,  strife  delicately  prickled  ; 
brownish  rose,   whitish  towards  the  umbo,  dotted 
with  black  and  scarlet,  spines  and  prickles  white. 
Hab.  Philippine  Islands. 

Distinguished  by  a  peculiar  tone  and  pattern  of  colour- 
ing, rayed  with  alternate  rows  of  white  spines  and  prickles. 


Species  62.  (Mus.  Cuming.) 
Spondylus  afpinis.     Spond.  testa  subtriz/ouo-omtd,  ra-

The  allied  Spondylus.     Shell  somewhat  triangularly 
ovate,  radiately  ribbed,  ribs  rather   distant,  armed 
with  rather  long  promiscuously  twisted   scales,   in- 
terstices with  five  rows  of  prickles  ;  brownish-purple, 
dotted  with  rose  about  the  umbo,  scales  wbit-e. 
flab.  Phihppine  Islands. 

Tills  species  has  very  much  the  appearance  of  -S'.  a/bt- 
barbatus,  the  scales  being  similarly  white  upon  a  dark 
ground,  which  in  the  present  species  has  a  more  purple 
tone,  while  the  umbo  is  rose-spotted.  The  chief  diiference 
is  in  the  more  rudely  angular  form  of  this  shell. 


Species  63.  (Mus.  Cuming.) 

Spondylus  aculeatus.  Spond.  testa  oblongo-ovatd,  valde

Operculum  testaceum,  seiniofalHiii,  apjii'iullce  laterall 
acuta  iuHiructum. 
Shell  subglobose,  generally  covered  with  an  olive  epider- 
mis,  spire  small,   lateral,   seldom    exserted ;    whorls 
sometimes  smooth,  sometimes  coronated  ;  columellar 
area  flat,  often  rather  large,  entire  at  the  margin ; 
apertnre  semicircnlar,  lip  more  or  less  diffused,  some- 
times dilated  on  both  sides.     Operculum  testaceous, 
semiovate,  furnished  with  a  sharp  lateral  piece. 
The  NerltiucB,  or  Freshwater  Nerites,  are  distinguished 
from  the  Nerilcc  proper,  or  Marine  Nerites,  chiefly  by  their 
more  gloomy  aspect,  thinner  substance,  and  absence  of 
sculpture  and  of  columellar  teeth ;  there  are,  nevertheless, 
some  species  of  extremely  brilliant  colouring,  and  some 
characterized  by  a  conspicuous  variously  developed  crown 
of  spines.     Considerable  attention  has  been  given  to  this 
genus  by  M.  llecluz,  and  by  Mr.  G.  B.  Sowerby,  jnu., 
both  in  his  '  Conchological  Illustrations '  and  in  bis  '  The- 
saurus Conchyliorum;'  but  the  additions  made  to  the  species 
from  various  sources  during  the  last  five   years  by  Mr. 
Cuming,  have  increased  the  number  one-half,  and  rendered 
a  further  monograph  desirable. 

The  NerUiiue  are  chiefly  inhabitants  of  the  Old  World, 
ranging  from  our  own  continent  and  islands  through  the 
islands  of  the  Pacific  and  Eastern  Seas  to  Australia  and 
New  Zealand.  In  the  New  hemisphere  the  genus  is  re- 
presented mainly  in  the  streams  of  the  West  Indies  aud 
Central  America.

Of  this  very  beautiful  and  extremely  variable  species,  it 
has  been  necessaiy  to  give  specimens  under  several  dif- 
ferent aspects  of  colouring.  The  predominant  colouring 
is  deep  rose,  variously  interrupted  with  bands  of  pale  yel- 
low, marked  with  regular  oblique  black  bands ;  but  these, 
as  it  may  be  seen  in  Fig.  88  k,  are  sometimes  absent, 
while  in  other  specimens,  as  at  Fig.  88  i,  the  black  bands 
are  conspicuous,  and  the  rose  colouring  is  wanting.

NATICA. 

Plate  I. 


Genus  NATICA,  Adcmson. 

Tenia  globosa  vd  neritoidea,  interdiim  aperti  bijlntii,  ^pird 
irevi,  scspisslme  rix  exsertu,  aiifractibiis  pa/tcia,  iimhi- 
licum  amplum  formantUms,  mine  caUosUute  dciiad  hn- 
pleto,  nunc  callodtate  colmnnari  qjiraliter  iidrantc, 
apertiird  plerumqiie  plus  miwu^  lunari.     Operculum 
interdum,  testaceim,  sapissinie  corneum,  spirale. 
Shell  globose  or  neritoid,  sometimes  openly  inflated,  spive 
short,  very  often  scarcely  exserted,  whorls  few,  form- 
ing a  large  umbilicus,  which  is  sometimes  filled  with 
a  dense  callosity,  sometimes  with  a  columnar  callosity 
entering   spirally,  aperture   generally  more  or  less 
lunar.      Operculum  sometimes  testaceous,  generally 
horny,  spiral. 
The  comparatively  recent  discovery  that  the  soft  parts 
of  Natica  are  similar  to  tliose  of  Si(jaretm,  requii-ed  that 
these  genera,  which  in  Lamarck's  time  wore  arranged  at 
some  distance  from  each  other  in  the  system,  should  be 
brought  into  more  immediate  relationship.     By  malacolo- 
gists,  indifferent  to  the  characters  of  the  shell,  the  Natica 
have  been  removed  to  the  Siffaivli ;  but  conchologists,  un- 
willing to  lose  sight  of  their  obvious  and  long-acknow- 
ledged affinity  in  this  respect  with  the  Nerites,  have  caused 
the  Sigareii  to  be  removed  to  the  Neritacea.     It  was  by 
the  French  navigators,  MM.  Quoy  and  Gaimard,  during 
the  voyage  of  the  '  Astrolabe,'  that  the  animal  portion  of 
Natica  was  first  fully  observed,  though  figm-ed  a  century 
before  by  Adanson.     Dift'ering  essentially  from  that  of 
Nerita,  it  proved  to  be  of  very  much  larger  dimensions 
in  proportion  to  the  size  of  the  shell,  distinguished  by  a 
broad  mantle-like  expansion  of  the  foot,  and  characterized 
by  a  more  or  less  thickened  circular  ridge,  holding  the 
shell,  and  sometimes  almost  concealing  it  from  view.    The 
Natica  has,  moreover,   a  retractile  proboscis,  which  the 
Nerite  has  not,  and  it  is  of  more  predaeeous  habits.     The 
lobe  which  carries  the  operculum  is  also  largely  developed 
and  reflected  over  the  shell.     The  animal  of  Sigaretius  is 
of  similar  structure ;  and  looking  alone  to  its  distinctive 
features  of  organization,  there  is  little  family  relationship 
between  it  and  the  typical  soft  parts  of  Neritacea. 

The  shells  of  Natica  are  not  particularly  variable  in 
form.  They  are  nearly  all  of  the  same  peculiar  semiglo- 
bose,  lunar-apertured  plan  of  convolution,  which  is  cha- 
racteristic of  the  Nerites,  mostly  largely  umbilicated,  but 
having  the   umbilicus  sometimes   filled  up    with   callous 


enamel,  and  sometimes  partially  filled  with  a  peeidiar 
spiral  columnar  callosity.  Little,  however,  as  this  varia- 
tion is,  the  Natica  have  been  divided  into  seven  genera  : — 
Natica  proper  {N.  canrena),  Liouitin,  Lamarck  (iV.  moidli- 
fera),  Neverita,  Kisso  {N.  alhiimeii),  Ampullina,  Lamarck 
{N.Jliwtuata),  Ruma,  Chemnitz  {N.  Maura),  Mamma,  Klein 
(iV.  mamiiiiUa),  and  Naticiiia,  Gray  (iV.  papilla).  The 
chief  conchological  distinction  between  the  genera  Nerita 
and  Natica  is,  that  whilst  the  Nerites  are  mostly  strongly 
grooved,  and  otherwise  sculptured,  and  richly  painted,  the 
Natica  are  smooth  and  polished,  as  is  almost  invariably 
the  ease  with  shells  more  or  less  enveloped  by  the  soft 
parts  of  the  animal,  and  painted,  generally  with  light  co- 
lours. 

The  Nulira'  live  mostly  in  sandy  and  muddy  beaches, 
at  about  low-water  mark,  and  are  strictly  caruivorous. 
Speaking  of  a  large  species,  N.  /leros,  inhabiting  the 
shores  of  Massachusetts,  Dr.  Gould  says,  in  his  history  of 
the  Invcrtebrata  of  that  State; — "This,  in  common  with 
other  species  of  Natica,  is  very  voracious,  and  plays  a 
conspicuous  part  in  devouring  the  dead  fish  and  other 
animals  which  are  thrown  up  by  the  tide.  Many  of  the 
shells  thrown  upon  the  shore  are  found  to  be  perforated 
with  a  small  round  hole :  this  is  done  principally  by  the 
difi'erent  species  of  Natica.  They  have  the  power  of  per- 
forating shells,  it  is  generally  supposed,  by  discharging  an 
acid  which  decomposes  the  shell,  and  through  the  aper- 
ture they  extract  the  juices,  and  destroy  the  lives  of  the 
otherwise  secure  inhabitants.  Their  foot  is  very  large,  so 
as  to  completely  envelope  the  objects  on  which  they  prey. 
In  moving,  they  burrow  in  the  sand,  so  as  to  be  almost 
entirely  concealed  by  it,  and  their  place  is  generally  indi- 
cated by  a  small  heap  of  sand.  The  singular  nidus  in 
which  the  animal  of  Natica  deposits  its  eggs  has  been  an 
object  of  much  curiosity  and  speculation.  It  is  a  mass  of 
sand  glued  together  into  the  shape  of  a  broad  bowl,  open 
at  the  bottom,  and  broken  at  one  side.  Its  thickness  is 
about  that  of  an  orange-peel,  easily  bent  without  breaking 
when  damp,  and  when  held  up  to  the  light  will  be  found 
to  be  filled  with  little  cells,  arranged  in  quincunx  order. 
Each  of  these  cells  contains  a  gelatinous  egg,  having  a 
yellow  nucleus,  which  is  the  embryo  shell."

This  fine  species  is  distinguished  from  its  congeners  of 
the  same  gigantic  dimensions,  by  its  more  depressly  glo-

This  fine  species,  distinguished  by  a  rather  light,  glo- 
bose form,  is  very  closely  allied  to  iV.  diipUcata,  so  near, 
indeed,  that  we  have  great  doubt  of  its  being  actually 
distinct.

This  fine  species  is  remarkably  characterized  by    its 

heavy  growth  and  monstrous  callosity.     The  shell  figured 

by  Dr.  Gould  at  No.  1G4  of  his  work  on  the  Invertebrata 

of  Massachusetts  as  a  variety  of  iV.  dupUcata  appears  to 

be  an  immatm-e  N.  Reclu:iaua.

This  species  scarcely  differs  from  N.  Iicros,  inhabiting 
the  same  locality,  except  in  being  of  a  more  oblong  form, 
which  is  of  doubtful  importance.     The  shell  iigured  by 
Dr.  Gould  for  this  species,  in  his  work  on  the  Invertebrata 
of  JIassachu.setts,  at  No.  164,  appears  to  be  N.  R('dii:iana.

NAVICELLA. 


Genus  NAVICELLA,  Lamarck. 
Ti'sia  oblomjo-ovata,  ckpressa,  Patellcpformis,  interdum  coii- 
centrice  striata,  sapius  lavigata,  olivaceo-lutea  vel  vi- 
rescens,  nigra  plerumque  reticulata,  spird  nulla,  vertice 
ad  marginem  suboblique  reflexo,  interdum  roslraio,  labro 
simplici,  area  columellari  tettui,pland,  septiformi,  aper- 
turd  perampld,   impressionibus   musculariius   duabus 
distinctis.     Operculum  testaceum,  mbquadratum,  pla- 
num, dente  laterali  aeuto. 
Shell  oblong-ovate,  depressed.  Patella-shaped,  sometimes 
concentrically  striated,  more  frequently  smooth,  olive- 
yellow  or  greenish,  generally  reticulated  with  black, 
no  spire,  vertex  rather  obliquely  inflected,  sometimes 
beaked,  lip  simple,  columellar  area  thin,  flat,  septum- 
like, aperture  very  largo,  muscular  impressions  two, 
distinct.     Operculum  testaceous,  nearly  square,  flat, 
with  a  sharp  toolh  at  the  side. 
The  Nnvicella  are  a  group  of  the  very  characteristic 
family  of  fresh-water  Nerites,  in  wliich  the  shell  assumes 
a  more  open  Limpet-like  form.     The  spire,  which  in  Ne- 
rlta  and  Neritina  is  convoluted  in  a  very  simple  manner, 
and  is,  in  some  species,  so  concealed  as  scarcely  to  show 
any  convolution,  is  here  transformed  into  the  simple  nu- 
cleus of  a  spire  with  the  vertex  inflected,  as  in  some  of 
the  Limpets,  into  a  beak.     The  callous  expansion  of  the 
columella,  typical  of  this  family,  which  is  often  so  broadly 
and  thinly  developed  in  Neritina,  is  in  Navicella  modified 
into  a  positive  septum  or  shelf,  forming,  so  to  speak,  the 
poop  of  the  little  boat. 

There  is  not  much  variation  either  of  form  or  painting 
in  the  Navicelhs.  They  are  mostly  of  an  olive-yellow  or 
gi-eenish  colour,  reticulated  or  blotched  with  black,  but  a 
few  are  semitransparent  and  tinged  with  rose.  Only  five 
species  were  known  to  Lamarck.  The  exploration  of  the 
rivers,  during  the  last  few  years,  in  the  islands  of  the 
Eastern  and  South-Eastern  Seas  have  brought  many 
more  species  to  light,  and  the  number  is  increased  to 
upwards  of  thirty.  The  Navicella:  are  not  found  in  Europe 
nor  in  any  part  of  the  Western  Hemisphere.  Their  chief 
habitats  are  the  Philippine  and  Australian  Islands,  the 
New  Hebrides,  New  Ireland,  and  New  Caledonia.

Of  a  peculiar  elongately  ovate  form,  obliquely  curved, 
with  an  eroded  sinus  on  the  inner  side,  which  seems  to 
indicate  that  this  sheH  may  prove  to  be  typical  of  a  new

LATIA. 


Genus  LATIA,  Gray. 
Testa  tennis,  subcornea,  ovata,  depresse  pileiformis,  vertice 
oblique  intorto,  ■subrosfrato ;  intus  septo  arcuato,  mar- 
giiie  subreflexo,  ad  extremitatem  imam  acute  producto. 
Shell  thin,  rather  horny,  ovate,  depressly  cap-shaped,  ver- 
tex obliquely  twisted  in  and  slightly  beaked ;  interior 
marked  with  an  arched  shelf,  a  little  turned  up  at  the 
edge,  which  is  sharply  produced  at  one  end. 
The  two  little  shells  here  figured  with  the  Navicdlre 
present   a   distinct   typical    character,   partaking   almost 
equally  in  the  general  features  of  convolution  and  texture 
with  Ancylus.     Dr.  Gray,  while  distinguishing  them  in 
our  national  collection  by  the  generic  title  of  Lafia,  places 
them  near  the  latter  genus ;  but  in  the  absence  of  any 
knowledge  of  the  animal,  their  position  in  the  system 
can  only  be  a  matter  of  conjecture.     They  are  of  thin, 
olive  or  greenish,  horny  substance,  with  the  spire  obliquely 
twisted  in,  having  an  opake  white  septum  in  the  interior, 
similar  in  a  measure  to  that  of  Navicella  or  Cahjptrea,  but 
presenting  a  peculiar  modification,  the  edge  being  slightly 
bent  upwards  and  prolonged  at  one  end  into  a  sort  of 
spine. 

Both  species  are  from  New  Zealand.

Gray,  MS.  Mus.  Brit.

This  species,  the  smaller  of  the  two  which  at  present 
constitute  this  genus,  has  the  vertex  the  more  swollen  and 
produced  in  proportion  to  the  size  of  the  shell. 


Species  2.  (Fig.  35  a,  b,  Mus.  Cuming.) 
Latia  lateealis.     Lat.  testd  subquadrato-ovaid,  subde-

Genus  SIPHONARIA,  Soicerby. 

Testa  oviita,  nunc  elevaio-conica,  verticc  iiiwinato,  i/iiiic  de- 
pressa,  radiathn  costata   re/  liiri/a.  ii/ari/ine  iloiticii-

caimU  phis  minus  distiiicli:  iiiilnilu. 
Shell  ovate,  sometimes  elevately  conical,  uncinate  at  the 
top,  sometimes  depressed,  radiately  ribbed  or  stri- 
ated, denticulated  at  the  margin.     Muscular  impres- 
sion  interrupted   in  front,   more  or  less  distinctly 
marked,  with  a  canal  leading  to  the  side. 
The  attention  of  Mr.  Sowerby  was  first   attracted  to 
this  group  of  Limpets,  as  distinguished  from  the  ordinary 
PaMla,  by  the  impressed  mark,  on  one  side  of  the  in- 
terior, of  an  outlying  siphon.     The  animal  was  succes- 
sively anatomized  by  De  BlainvUle  and  M.  Quoy,  and  a 
structure  corresponding  with  this  mark  was  found  to  exist 
iu  the  form  of  a  caual,  used  for  the  conveyance  of  water 
to  the  branchial  cavity,  which  proved  to  be  situated  iu 
the  back  of  the  neck.     The  first  recognized  species  were 
described  and  figured  by  Mr.  Sowerby,  in  his  '  Genera  of 
Shells.'     The  soft  parts  were  figured  by  M.  Quoy  in  the 
'  Voyage  de  TAstrolabe,'  but  several  of  the  shells  named 
iu  that  work  as  distinct  species,  and  reproduced  as  such 
by  M.  Deshayes  in  his  edition  of  Lamarck's  '  Animau.K 
sans  vertebres,'  appear  to  be  varieties  of  one  and  the  same 
species  in  different  states.     With  the  aid  of  a  numerous 
series  of  specimens  of  SlpJionaria,  collected  together  by 
Mr.  Cuming,  I  have  been  enabled  to  define  many  new 
species,  and  remove  previous  errors,  the  whole  forming  an 
exceedingly  natural  group,  all  readily  distinguished  by  their 
variations  of  form,  sculpture,  and  internal  colouring. 

The  Siphonar'uB,  as  will   be   seen  on  reference  to  the 
habitats,  are  widely  distributed  in  both  hemispheres. 


Species  1.  (Fig.  u,  h,  ^lus.  Cuming.) 
SiPHON.\RiA  DiEJiENENSis.  Sipli.  testd  ovatd,  convexd, 
vertice  aeiito,  radiaiim  costatd,  cosiis  numerosis,  rudi-

yinem  cinefeo-nifesceiifibus,  niuri/ini'  iiitiis  conspici'i 
castmieo  albogue  lineolato. 
The  Van  Diemen's  Land  Siphonaria.  Shell  ovate, 
convex,  sharp  at  the  top,  radiately  ribbed,  ribs  nume- 
rous, rude,  irregular ;  ribs  white,  interstices  ash-red 
towards  the  margin,  margin  conspicuously  lincated 
withiu  with  chestnut  and  white.

pi.  25.  f.  1-13. 
IM.  Van  Diemen's  Land. 

Au  acutely  convex  species,  irregularly  closely  ribbed, 
with  the  interstices  excavately  grooved,  and  further  dis- 
tinguished by  the  inner  margin  being  conspicuously  tes- 
sellated. 


Species  2.   (Fig.  ff, /a  Mus.  Cuming.) 
Siphonaria  scabra.     Sijili.  testd  ortjicidari,  subdepresse

terstices purple-brown,  interior  purple-liiieated. 
Jlab.  Port  Jackson,  Australia. 

Of  a  more  orbicular  form  than  the  preceding  species, 
with  the  ribs  more  rough  and  irregular,  and,  the  shell 
being  of  thinner  substance,  the  purple  linear  painting  is 
seen  running  up  further  in  the  interior. 


Species  3.  (Fig.  <i,  b.  Mus.  Cuming.) 

Siphonaria  gigas.  Siph.  testa  elevato-cuiicexd,  radia- 
tim fortiter  costatis,  cosiis  rude  aiigulatis,  aciitis,  in-

tinctd. 

The  giant  Siphonaria.  Shell  elevately  convex,  radi- 
ately strongly  ribbed,  ribs  rudely  angled,  sharp,  in- 
terstices striated;  brown,  stained  with  black  towards 
the  margin. 

Sowerby,  Tankerville  Catalogue,  App.,  p.  vii.  n.  SOS. 

Hab.  Galapagos  Islands  and  Panama. 

This  fine  species  is  well  distinguished  by  its  strong, 

rude,  angularly  raised  ribs,  radiating  from  the  top  like 

buttresses. 


Species  4.   (Fig.  a,  b,  Mus.  Cuming.)

This  species,  of  which  fine  specimens,  such  as  those 
figured,  were  collected  in  abundant  variety  by  Mr.  Cuming 
at  the  Philippine  Islands,  differs  materially  in  the  character 
of  its  sculpture,  the  ribs  being  sometimes  numerous  and 
close-set,  as  in  Mr.  Sowerby's  typical  specimen,  sometimes 
distant,  with  small  intervening  ridges,  as  in  S.  exigua  of 
the  same  author.

Genus  NEHITA,  Linndna.

Uler  costatis  vel  liratis,  aperturd  semioriicidari,  labro 
intus  crenaio-lirato,  interdmn  ad  latirra  dcnticulato, 
area  colimiellari  subampld,  sape  granulatd  aid  corrii- 
gatd,  ad  marginem  plernmqne  dentatd ;  colore  raria, 
sapissime  vivide  picta  ;  operculo  iedaceo. 
Shell  globosely  ovate,  spire  rarely  exserted,  whorls  rather 
compressly  convoluted,  sometimes  smooth,  generally 
spirally  ribbed  or  ridged,  aperture  semiorbicular,  lip 
crenately  ridged  within,  sometimes  toothed  at   the 
sides,  coIumcUar  area  rather  large,  often  granulated 
or  wrinkled,  generally  toothed  at  the  margin ;  colour 
various,  mostly  brightly  painted ;  operculum  testa- 
ceous. 
The  Sea  Nerites  liave  always  been  a  favourite  tribe  of 
sheOs  among  eoUeetors,  on  account  of  their  pretty  varie- 
ties of  painting.     The  animal  of  the  Freshwater  Nerites, 
which  I  propose,  contrary  to  the  opinion  of  some  con- 
chologists,  to  associate  still  under  the  head  of  Neritbia,  is 
the  same,  but  the  shell  is  of  lighter  structure  and  of  more 
sombre  hue.     From  Natica  the  shell  of  Nerifa  dill'ers  in 
being  more  sculptured  and  more  brilliantly  coloured,  and 
the  columellar  area  is,  with  few  exceptions,  toothed,  and 
either  grained  or  wrinkled.     The  genus  has  been  well  ex- 
amined by  M.  Eecluz,  but  severa'  of  his  species  I  have 
been  unable  to  identify  for  want         );ures.     Fortunately 
the  types  of  most  of  this  French  concliologist's  species  are 
in  the  collection  of  Mr.  Cuming,  who  confided  his  'speci- 
mens to  him  about  fifteen  years  since  for  description.   The 
species  which  are  named  for  the  first  time  in  the  following 
Monograph  have  accumulated  since  that  period. 

The  Nerilte  are  most  abundant  in  the  ^Molucca  and 
Philippine  Islands,  and  New  Zealand  and  Australia  con- 
tribute some  fine  species.  A  few  species  inhabit  the  shores 
of  Central  America  and  the  West  Indies,  but  the  genus  is 
not  represented  generally  in  the  New  World.  The  species 
are  less  numerous  than  those  of  Neritiiia,  and  there  are 
few  of  small  size. 


Species  1.  (Fig.  a,  b,  Mus.  Cuming.)

The  snake-skin  Nerite.  Shell  ovate,  thick,  flatly  ex- 
cavated beueath,  spire  minute,  lateral,  superficial, 
sharp  at  the  apex,  whorls  rather  narrowly  rounded, 
spirally  ribbed,  ribs  narrow,  raised,  intermediate 
grooves  broad,  conspicuously  excavated,  with  a  small 
central  ridge  running  through  them,  interior  of  the 
aperture  ridged,  columella  very  broadly  concave,  gra- 
nulated, and  minutely  toothed  in  the  middle  at  the 
edge ;  ribs  blue-black,  sparingly  marked  with  white 
lines,  grooves  whitish,  spotted  with  blue-black,  colu- 
mellar area  fulvous-tinged.

Much  confusion  has  arisen  through  confounding  the 
well-known  N.  plexa  of  Chemnitz  with  the  Linna'an 
'N.  exuvia;  but  the  description  "  nigricans  lineis  transversis 
albidis  "  in  the  careful  diagnose  above  referred  to,  does 
not  apply  to  that  species.
